I had this question after viewing Import .csv file into Exchange Distribution Group
I've got 200 email addresses to put into a newly created DL. I've tried using the script in the above case (making appropriate changes) and I get the attached error. The name of the DL is Blackstone Consultants, the .csv file is BlackstoneGroup.csv and is saved on the hard drive in the temp folder. How can I adjust the script to get it to work?
